Abstract

Here we present the Combretaceae flora for Rio Grande do Norte state, Northeastern region of Brazil, based on morphological analyses of specimens deposited in the herbaria ASE, EAC, FUEL, HEPH, HST, HUEFS, IPA, JPB, MAC, MBM, MOSS, NY, UEC, and UFRN, bibliography and images of type specimens. Twelve species belonging to five genera are recorded: Buchenavia (1 sp.), Combretum (7 spp.), Conocarpus (1 sp.), Laguncularia (1 sp.) and Terminalia (2 spp.). Combretum duarteanum, C. fruticosum, and T. mameluco are considered new records for the state while Terminalia cf. amazonia may also be a new record depending upon the collection of complete specimens to have its identity confirmed. Identification keys to genera and species, descriptions, geographic distribution, taxonomic comments and illustrations are provided.
